AerialAccess. This web mapping application is a collection of current and historic aerial photos dating back to 1936. The application allows users to select two flight years and overlay them to see what changes have occurred over time. A time sequence print out is also available. Be sure to read the 'Info' and 'Basics' sections in the application to obtain a better understanding of the aerial photos being viewed.

Enterprise GIS
Dutchess County has developed an Enterprise-wide GIS.  The basic mandate for any enterprise GIS application is to ensure that all agencies within an organization have access to GIS information so that they can operate at a higher efficiency. An enterprise GIS provides greater consistency and accuracy from system-wide management, more efficient use and sharing of data, reduced redundancy of data across the system, better use of departmental GIS resources, and reduced maintenance and support costs.
Public Workstations:
Options are available for individuals wanting to access the web applications other than from home.  There are numerous public workstations throughout the County.  There are public workstation available at:
